RP-U06
Small-membrane RO with built-in tank — four options. Dual-engine leads the series.
RP-U06 is a small-membrane, built-in tank RO family: a compact RO membrane paired with an internal water tank, so the tank delivers high flow without a large membrane. Four options share the same idea and differ in tank size, membrane and heating — the dual-engine (400G membrane, 2L pressure tank, dual drinking + kitchen-wash outlets, 1.05 L/min pure-water flow); the 4.1L tank (100G, 4.1L built-in pure-water tank, 4–9 L/min); the 8L tank (50–150G, 8L built-in tank with UV, 2.5–5 L/min, with an optional 4-temperature instant-heating version); and the 7.5L tank (75/100G, 7.5L built-in pure-water tank with static UV, 5 L/min, side plug-in cartridge change, with an optional faucet thick-film heating version). Specifications are confirmed per model and order.
Voltage / frequency is configurable to the target country. Other configurations are confirmed per order.
About RP-U06
RP-U06 is a small-membrane, built-in tank RO family: a compact RO membrane paired with an internal water tank, so the tank delivers high flow without a large membrane. The lead option is the dual-engine (400G membrane, 2 L pressure tank, dual drinking + kitchen-wash outlets, 1.05 L/min pure-water flow, with an initial flow of over 4.2 L/min in the first 3 seconds). Three further options share the same idea: a 4.1 L tank (100G, 4–9 L/min), an 8 L tank with UV (50–150G, 2.5–5 L/min) and a 7.5 L tank with static UV (75/100G, 5 L/min). All four options have a rated purified volume of 4000 L.
Why buyers choose it
- High flow from a small membrane: the dual-engine pairs a 400G membrane with a 2 L pressure tank, giving 1.05 L/min pure water and over 4.2 L/min in the first 3 seconds.
- Dual outlets on the dual-engine: drinking water and kitchen wash water from one unit, with a grey mechanical faucet with knob control.
- Grade 1 water efficiency on the dual-engine, with a net-water production rate of 0.65 and a desalination rate of ≥93%.
- Four tank options: dual-engine (400G), 4.1 L tank (100G, 352 × 160 × 319 mm), 8 L tank with UV (50–150G, optional 4-temperature instant heating at 2100 W, 20 L/h) and 7.5 L tank (75/100G, static UV 99.9%, 415 × 187 × 392 mm).
Best for
- Kitchens that need high flow under the sink without a large RO membrane.
- Homes that want separate drinking and kitchen-wash outlets from one unit.
- Brands that want a tank RO family with a heating option for the premium end.
